mysqld_safe启动报错

mysqld_safe --user=mysql &

报错（如下），但是使用mysqld直接启动没有问题。

说明：mysqld_safe启动脚本默认的从/usr/local/mysql目录中读取另外一个启动脚本mysqld，因为我的安装目录为/home/mysql/product/5.6/mysql-1。所以找不到相关文件。可以从两个方面解决。

方法一：在/usr/local/mysql创建链接文件

mkdir -p /usr/local/mysql/bin
ln -s /home/mysql/product/5.6/mysql-1/bin/mysqld /usr/local/mysql/bin/mysqld

方法二：将mysqld_safe中的所有/usr/local/mysql目录改为自己实际的安装目录

sed -i 's#/usr/local/mysql#/home/mysql/product/5.6/mysql-1#g' /home/mysql/product/5.6/mysql-1/bin/mysqld_safe
